I am now working on adding some global key shortcuts to my application.

First, I’ve written a method to translate native modifier codes to swing’s modifier codes, added a global native hook, but it did not work. Than, I’ve added a print-statemenet and encountered an unexpected result.

Code:

int m=KeyEvent.SHIFT_DOWN_MASK|KeyEvent.CTRL_DOWN_MASK|KeyEvent.ALT_DOWN_MASK;
System.out.println(m+" "+KeyStroke.getKeyStroke(KeyEvent.VK_SUBTRACT,m).getModifiers());

Output: 704 715.

So… Why? Why modifiers set are not what getter returns?
I reckon, it should return 704 704.
